Need to add a "Wait" command to a Powershell script

  • 772

Here is my current code:

Write-output “ENTER THE FOLLOWING DETAILS - When Creating Multiple New Accounts Go to           EMC hit F5(refresh) and make sure previous new account is listed before proceeding to the       next one”
$DName = Read-Host “User Diplay Name(New User)"
$RUser = Read-Host "Replicate User(Database Grab)"
$RData = ((Get-Mailbox -Identity $RUser).Database).DistinguishedName
$REmailInput = Read-Host “Requester's Name(Notification Email goes to this Person)"
$REmail = ((Get-Mailbox -Identity "$REmailInput").PrimarySmtpAddress).ToString()

Enable-Mailbox -Identity "$DName" -Database "$RData" 
Set-CASMailbox -Identity "$DName" -ActiveSyncEnabled $false -ImapEnabled $false -    PopEnabled $false


Send-MailMessage -From "John Doe <[email protected]>" -To $REmail -Subject       "$DName's email account" -Body "$DName's email account has been setup.`n`n`nJohn Doe`nXYZ`nSystems Administrator`nOffice: 123.456.7890`[email protected]" -SmtpServer [email protected]

This code works flawlessly about half the time, but the other half I get this error in return:

ENTER THE FOLLOWING DETAILS - When Creating Multiple New Accounts Go to EMC hit
F5(refresh) and make sure previous new account is listed before proceeding to
the next one
User Diplay Name(New User): Jane Doe
Replicate User(Database Grab): Julie Doe
Requester's Name(Notification Email goes to this Person): Joanna Doe

Name                      Alias                ServerName       ProhibitSendQuo
                                                            ta

Jane Doe                  JDDAFA               [email protected]      unlimited
Set-CASMailbox : Jane Doe is not a mailbox user.
At C:\emailclientbasic.ps1:11 char:15

mentObjectNotFoundException

So if anyone could help me throw in some kind of wait command after the mailbox is created and wait until the user's mailbox is created before the script disables ActiveSync, etc it would be really helpful. I believe that simply using the -wait switch does not work.

    Use the Start-Sleep command: 

    Start-Sleep -s 10

    will pause the script for 10 seconds.

  2. I had to deal with some timing in an Exchange script I wrote a while ago. Specifically, I needed to modify permissions on a newly created distribution group, but needed to wait until the distribution-group was actually created before attempting to modify it.

    do {
    sleep -seconds 1
    $mailboxExists = get-mailboxpermission -Identity "CN=$displayName,$DN" -User "NT AUTHORITY\SELF" -ErrorAction SilentlyContinue |fw IsValid
    write-host "." -nonewline
} while (!$mailboxExists)

    It just attempts to get the "IsValid" attribute off of the mailbox (in this example) as a proxy for "mailbox exists". Once get-mailboxpermission returns true, the next step, setting a permission will actually function. The write-host is just to provide a progress bar.

  3. You could run it as a background job and then wait for that job to finish. Like this:

    $enablemb = Start-Job { Enable-Mailbox -Identity "$DName" -Database "$RData" }
    Wait-Job $enablemb
    Receive-Job $enablemb

  5. Why not something like:

    do {
$testpath = Test-Path -path \\dns2\d$\test
}
until ($testpath -eq $true)

    I use this type of command with an addtional start-sleep after the initial test because do until eats a lot of processor cycles without it. So mine looks more like this:

    do {
$testpath = Test-Path -path \\dns2\d$\test
start-sleep -s 10}
until ($testpath -eq $true)

    If the test is going to change state quickly when do not worry about the start-sleep.
